Abstract
Due to the large available bandwidth, the communications in the terahertz band (0.1 THz − 10 THz) is one of the key techniques to meet the Tbit/s rate requirements of the future wireless networks. The propagation in the mentioned frequency range is subject to high path losses, presents a low diffractive capacity and is susceptible to diffuse scattering. Thus, in order to characterize the channel in the range from 0.2 THz to 0.3 THz, this work presents results of ray tracing simulations in an indoor environment. The ray tracing is based on the shooting-and-bouncing rays method and characterizes the propagation by means of reflections, diffractions, diffuse scattering and atmospheric molecular absorption. From the simulation results, the path losses, the Rice factor, the root-mean-square delay spread and the channel coherence band are evaluated.
